From ICON
ICON Vehicle Dynamics V.S. Series 2.5" coilover shocks are an incredible upgrade for the front-end of 2019-2026 Chevrolet Silverado 1500/GMC Sierra 1500 trucks. Their extended length and pairing with ICON front upper control arms offers an increase in total front wheel travel compared to ICON standard travel coilovers, for a total of approximately 10" of front wheel travel. ICON's vehicle-specific valving provides a sport tuned feel on and off-road while 1.5-3.5" of lift height adjustability allows the use of larger, more aggressive wheel and tire combinations. The larger 2.5" diameter shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. When paired with ICON rear 2.0 Aluminum Series or 2.5 Series shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your GM pickup.
Why this 2.5 Series VS IR Front Coilover Kit
ICON 2.5 Series coilovers replace the factory strut with a threaded-body, vehicle-specific unit for the 2019-2026 Chevy/GMC 1500. Ride height is set on the spring collar within the listed range, and damping is valved for this truck rather than a generic length.

Questions
IR, RR, PB: what is the difference?
IR is an internal reservoir, a self-contained monotube body. RR is a remote reservoir connected by hose and PB is a piggyback reservoir bolted to the body; both add oil volume and cooling so damping stays consistent on long rough sections. IR is lighter and simpler; RR and PB resist fade.
CDCV, CDEV, CDXS: which adjuster?
CDCV is a 10-position manual compression knob. CDEV is an electronic compression valve controlled by the ICON Intelligent Control module and phone app, which reads speed and terrain and adjusts on the fly; it requires the IIC install kit. CDXS is a manual dual-circuit adjuster with 10 marked detents each for compression and rebound. Shocks without a code run ICON's fixed vehicle-specific valving.
Can these be serviced?
Yes. Every ICON shock and coilover is rebuildable and revalveable through ICON factory shock service. The shock warranty is 12 months against manufacturing defects.
Do I need an alignment?
Yes. Any change to front ride height requires a four-wheel alignment after installation.
Do I need upper control arms?
ICON recommends aftermarket upper control arms once front lift exceeds roughly 2 in on independent-front-suspension trucks, to restore alignment range and ball joint angle. The Stage 2 and higher systems for this truck include them.
Who installs it?
ICON requires professional installation and does not cover failures caused by improper installation. Plan on a shop with a lift and an alignment rack for anything that changes ride height.
